Public Member Functions
	V3d_Plane (const Standard_Real theA=0.0, const Standard_Real theB=0.0, const Standard_Real theC=1.0, const Standard_Real theD=0.0)
	Creates a clipping plane from plane coefficients.
void	SetPlane (const Standard_Real theA, const Standard_Real theB, const Standard_Real theC, const Standard_Real theD)
	Change plane equation.
virtual void	Display (const Handle< V3d_View > &theView, const Quantity_Color &theColor=Quantity_NOC_GRAY)
	Display the plane representation in the chosen view.
void	Erase ()
	Erase the plane representation.
void	Plane (Standard_Real &theA, Standard_Real &theB, Standard_Real &theC, Standard_Real &theD) const
	Returns the parameters of the plane.
Standard_Boolean	IsDisplayed () const
	Returns TRUE when the plane representation is displayed.
const Handle< Graphic3d_ClipPlane > &	ClipPlane () const
	Use this method to pass clipping plane implementation for standard clipping workflow.
Public Member Functions inherited from Standard_Transient
	Standard_Transient ()
	Empty constructor.
	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.
Standard_Transient &	operator= (const Standard_Transient &)
	Assignment operator, needed to avoid copying reference counter.
virtual	~Standard_Transient ()
	Destructor must be virtual.
virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.
Standard_Boolean	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.
Standard_Boolean	IsInstance (const Standard_CString theTypeName) const
	Returns a true value if this is an instance of TypeName.
Standard_Boolean	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
Standard_Boolean	IsKind (const Standard_CString theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
Standard_Integer	GetRefCount () const noexcept
	Get the reference counter of this object.
void	IncrementRefCounter () noexcept
	Increments the reference counter of this object.
Standard_Integer	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value.
virtual void	Delete () const
	Memory deallocator for transient classes.

Detailed Description

Obsolete clip plane presentation class. Ported on new core of Graphic3d_ClipPlane approach. Please access Graphic3d_ClipPlane via ClipPlane() method to use it for standard clipping workflow. Example of use:

Handle(V3d_Plane) aPlane (0, 1, 0, -20);
Handle(V3d_View) aView;
aView->AddClipPlane (aPlane->ClipPlane());
 
aPlane->Display (aView);
aPlane->SetPlane (0, 1, 0, -30);
aView->RemoveClipPlane (aPlane->ClipPlane());

Use interface of this class to modify plane equation synchronously with clipping equation.
